Abstract
X-ray reflection gratings placed in the off-plane mount are capable of achieving high diffraction efficiency and high spectral resolving power, the two chief assets of a grating spectrometer. Developments in this technology have been accelerated in recent years and new fabrication methodologies are being employed to create a new generation of reflection gratings. Here, we discuss the theory of diffraction, and how it pertains to off-plane gratings. This is followed by a discussion of considerations that are relevant when designing an off-plane grating spectrometer. Empirical results from the measurement of diffraction efficiency and spectral resolving power are also presented to motivate a discussion of the incorporation of these gratings into future space-based X-ray spectrometers.
